ADC120 GAC Actuator Series Actuator:

• Rotary output linear torque proportional servo

• Small, low cost, low friction model

• 1.0 lb-ft of torque, 25° rotation, < 32 msec. response

• Suitable for rotary or small inline fuel pumps of small carburetors

• Ideal for fuel systems on engines up to 150 HP

The GAC Generator Actuator ADC120-12 is a rotary output, liner torque, proportional servo. This electromechanical actuator is typically used as an engine fuel control positioning device. An internal spring provides fail safe operation by forcing the GAC Generator Actuator ADC120 to the fuel shut off position when the actuator is de-energized. This design combines fast operation, multi-voltage usage, wider rotation angles, and proven reliability. The GAC ADC120-12 Generator Actuator can operate directly from 12, 24, or 32 volt battery supplies.

The speed of operation of the GAC ADC120 Generator Actuator is typically faster  than competitive units, thus it provides more stable and rapid response to transient conditions.

Applications include most block pumps, with or without mechanical governors, distributor type pumps, and medium sized carbureted engines. The 25 degrees of rotation expands the application to a wider variety of engines.

The GAC Engine Actuator ADC120-12 is an electromagnetic servo device which can be intergrated into a closed loop control system. An engine control system can be described as follows. An electrical signal is generated by a magnetic speed sensor which is proportional to engine speed setting are not equal, a change in current from the speed control unit to the actuator will change the magnetic force in the actuator.

The rotation of the actuator shaft will then adjust the fuel to the engine and cause the engine speed to be equal to the preset engine setting. Shaft rotation is proportional to the amount of actuator current and counterbalanced by the internal spring.

Since the design has no sliding parts and is totally sealed, outstanding reliability results. A single compression spring is used to improve reliability. No maintenance is necessary.
